Abstract
Gasified particles for cosmetic treatments, particularly hair treatments, are described. The gasified particles contain at least one gas enclosed in a solid enveloping material. The enveloping material is selected so that the gas is released on contact of the enveloping material with water or moisture. The release of the gas can be accompanied by a detectable acoustic effect (pop effect). The hair treatment composition also can provide a hair fixing effect. Furthermore an instant gel preparation is described substantially comprising a mixture of dry substances, which contains at least one gel former and at least one solid substance producing a detectable acoustic effect on contact with moisture, especially gasified particles. The gasified particles are used as acoustic indicators for the readiness of the instant preparation after liquid addition.
